Here's another game to help lighten up the threads a bit（In addition to that shiritori game). It's a word association game, where you take the previous word, and you give a word you link with it. For example if you start with りんご apple, then it might go to 赤い（あかい）red which then might go to 血（ち）blood. apple>red>blood>injury>sport>baseball>bat>hit>run>walk＞lazy>That type of progression. It's actually really fun and you get some funny combinations based on what you think of what you see the word.
